First of all, you might want to consider a more descriptive title, screaming HELP usually annoys the hell out of people, especially me.

It also wouldn't hurt to provide some more detail and to use the search engine.

React it with NaH in the correct proportions (carefully), and collect the gasses. CH3Cl boils at -24 deg C...
Not a pretty method though.

You mean to say youve NaH at your disposal?

Chemoleo - dont be sarcastic




F. de Lalande and M. Prud'homme showed that a mixture of boric oxide and sodium chloride is decomposed in a stream of dry air or oxygen at a red heat with the evolution of chlorine.

Ok, maybe I'm overstepping my bounds here, but I can't help but wonder why the hell this thread is even still open. It seems to me that it violates several rules that polverone has set out, like not screaming "Help, I dont want to do any of the work myself or actually learn chemistry I just want to have all the answers spoon fed to me."

In fact, the only reason I can think of this being left open is to heckle the thread starter, hence the vague and sarcastic remarks throughout.

I cant be the only one wondering why this thread hasnt been closed.

And just to attempt to be on topic and hopefully therfor not a hypocrit, the answer to the question is pretty clear. Dichloromethane to methyl chloride? NO. Methyl chloride can be economically made a number of ways, but this isn't one of them. Look for similiar reactions involving other halides.

I think it should be noted though that methyl chloride isnt a very good reagent for either methylations or grignard reagents.

Ouch, this one must have slipped through. Thanks for the reminder.

Closed.
